Prepare for the DevOps Engineering on AWS Certification exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: Which CodeDeploy appspec.yml section defines the scripts to run at each lifecycle event hook for an EC2 deployment?
Answer: B. Hooks
Explanation:
The correct answer is Hooks. In an EC2 CodeDeploy appspec.yml, the Hooks section maps each lifecycle event, such as stopping the application or validating the service, to the scripts that run at that point.
Resources is wrong because it describes deployment targets for other compute platforms, not scripts for EC2. Files is wrong because it only tells CodeDeploy which files to copy and where. Permissions is wrong because it sets ownership and mode on the copied files, and does not run anything.
Rule to remember: Files places content, Permissions adjusts it, and Hooks runs your code at lifecycle events.
Question: In AWS CodeDeploy, what deployment configuration gradually shifts traffic from the original to the replacement environment?
Answer: B. Blue/green deployment
Explanation:
Blue/green is correct because it creates a replacement environment next to the original and then shifts traffic to it, which lowers downtime and makes rollback simple.
In-place is wrong because it updates the instances already serving traffic. Rolling is wrong because it is a variation of in-place, updating the existing fleet in batches. Canary is a tempting choice, but it describes how traffic is shifted in steps, as a deployment configuration, and not the type of environment replacement the question asks about.
Rule to remember: if a separate replacement environment receives traffic, think blue/green. If the same instances are updated, think in-place.
Question: Which AWS service provides managed service discovery for microservices running on ECS or EC2?
Answer: A. AWS Cloud Map
Explanation:
AWS Cloud Map is correct. You register application resources under custom names, and services look each other up dynamically as instances come and go.
Route 53 is wrong because it is a DNS service for domain names, not a registry that tracks the changing set of service instances. App Mesh is wrong because it controls and observes traffic between services but is not the registry itself. Elastic Load Balancing is wrong because it spreads incoming traffic across targets and does not provide named discovery.
Rule to remember: match the verb. Discovery and registration point to Cloud Map, DNS points to Route 53, traffic control points to a mesh, and distribution points to a load balancer.
Start with the official exam page and its content areas, and note which ones you rarely touch in your own work. Those are your weak spots.
Take a mixed set from our list to get a baseline, then move to the topic sets. For each wrong answer, write down the rule you missed, not just the right option. Group those notes by content area so patterns show up, such as confusing deployment types or mixing up monitoring tools.
Back your practice with hands-on work in an AWS account: build a pipeline, deploy a CloudFormation stack, break it, and read the logs and alarms. Practice questions test judgment between similar services, and building things is the fastest way to learn that judgment.
Close each study session by rereading the relevant AWS documentation for the topics you missed. In the last days before the exam, redo only the sets where you still miss questions, then rest. Remember the exam is long, so practise answering in timed sittings to build stamina.
The exam has 75 questions, either multiple choice or multiple response, and you have 180 minutes to finish. Multiple response questions need every correct option selected, so read the instructions on each item carefully before answering.
The passing standard is a scaled score of 750, which applies to Professional-level and Specialty exams. The score is scaled, so it is not a simple percentage of questions answered correctly.
The fee is $300 USD per attempt, and local cost may vary with foreign exchange rates. You can sit the exam at a Pearson VUE testing center or take it online with a proctor. Check the official pricing page before you book.
You must wait 14 calendar days after a failed attempt before you can retake the exam. There is no limit on the number of attempts, but each attempt requires paying the exam fee again.
It is valid for 3 years. Before it expires, you can renew by passing the latest version of the exam or by maintaining the certification on AWS Skill Builder.
There are no formal prerequisites, but 2+ years of AWS experience is recommended. Hands-on time with pipelines, CloudFormation, monitoring and incident response will make the questions much easier to reason about.
